Smoke-consumer



INTTED STATES PATENT OEEICE W'ILLIAM VOGEL, OF CHICAGO, ILLINOIS.

SiVlOlE-CONSUIJIER.

SPECIFICATION forming part of Letters Patent No. 3lO,l56, dated December30, 1884.

Application tiled May 3i, 15S-l.

T 0 all whom, it may concern:

VBe it known that I, VTLLLIM VOGEL, of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin SmokeGonsumers; and Ido hereby declare the following` to be a full,clear, and exact description of the invention, such as will enablgothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in smoke-consnmers, and itconsists in the combination of a chimney or stack with the pipe downthrough which the products of combustion are made to pass, and in whichpipe are placed suitable water-jets for the purpose of cooling andcondensing the smoke, after which the smoke is passed through the burnerinto the furnace, where it is consumed, as will be more fully describedhereinafter.

The object of my invention is to cool the products of combustion afterthey have passed through the chimney or stack, and then pass themdirectly back to the fire, where all the waste gases are consumed asfuel, withoutany smoke being allowed to escape into the air.

Figure l represents a side elevation of a chimney or stack to which myinvention is applied. Fig. 2 is a vertical section of the same. Fig. 3is an enlarged detail view of the pipe through which the products ofcombustion are made to pass, and showing the water-jets and otherdevices used for acting upon the pro ducts of combustion. Figs. 4, 5, G,7, and S are details of construction. Figs. E) and l() show differentforms of chimneys or stacks to which my invention is applied.

A represents an ordinary furnace in connection with a steam-boiler, B,and C is the chimney or stack, which is connected with the furnace, andthrough which the products of comv bustion ascend in the usual manner.Upon the top of this chimney or stack is formed a chamber, I), which mayeither be of the form here shown or any other that may be preferred, andin which is placed a partition, E. This partition divides this chamberinto two parts, the one, G, of which is the chamber in which theproducts of combustion receive their first cooling.

(Xo model.)

For the purpose of cooling the smoke a water-pipe, I-I, which isconnected to the waterinain or any other suitable source of supply, ismade to extend upward to any desired height along` either the chimney Gor the pipe I, through which the products of combustion are made to passon their way back to the furnace. The chimney C and pipe I need not'necessarily be much over twenty feet, so that the pressure from thewater-main will readily supply all the water that is necessary t0condense the slnoke. From this pipe I'I,at its upper end,is forced a jetof fine spray at I,which, meeting the heated products of combustion asthey pass into the chamber G, cools them and causes them to descend fromtheir own gravity, The water which is discharged from the jet J fallsback into the pipe I and is conducted by means of the funnel L into achamber, reservoir, or receptacle, N, which is secured to and made torevolve with the screwshaft O, rIhe screw-shaft O is nrade hollow, andprojecting out from it over the blade of the screw are suitable smalljets,l?, from which the water is freely discharged, as shown in Fig. '7.rlhis water serves to cool the products of combustion still more, andthe back action from the water,not only from these jets I), but from theweight of the water which falls upon the'screw,causes it to revolvefreely around in its bearings at 0. falso, extending from the water-pipeII are suitable pipes,R, from which extend suitable jets, R, whichdischarge water into the pipe I in the form of fine spray. Thewhole'interior of the pipe being filled at certain points with iinespray, all of the products otl combustion become thoroughly dampened andcooled in their passage through the pipe. I here will be any number ofrevolving screws and water-tanks, N, and any suitable number of jetsarranged one above the other, as shown. After the products of combustionpass beyond this revolving screw or screws, which serve to causedownward drafts in the pipe I, they pass through the pipe S to theburner T, which is arranged upon the top ofthe grate-bars, as shown inFigs. l and 6, from whence the gases pass directly into the iire in thefurnace. lThe gases escaping directl y into the fire form so muchaddition to the fuel. All the fresh air which is necessary IOO toperfect combustion passes through the gratehars in the usual manner.After the products of combustion leave the furnace they are returned tothe furnace again for consumption, but none of them escape into the airat any point.

By means of a smoke-consumer constructed as here shown and described theair never becornes vitiated with smoke or soot7 and agreat saving ismade in the consumption of fuel. The Water which is used in cooling theproducts of combustion being taken directly from the water-main, nopower of any kind is neeessary in operating` devices of any kind. Assoon as the fire is lighted the Water is turned on and the operationofthe furnace begins at once7 and it is not necessary to allow smoke toescape until steam has been raised for the purpose of driving a motor.It is not neces` Sary that the pipe I should extend up the full heightof the chimney or stack, as shown in Fig. 9.

In case it is desired to apply my invention to one of the tall stacks orchimneys already in use, it will only beneeessary to attach the pipe Iand the Water-pipes connected to this pipe to the side of the stack, andthen Close the top of the stack, so as to prevent the escape oftheproducts oi" combustion at this point.

In Fig. l() is shown another form of my invent-ion, Where the chimney orstack C and the pipe I are formed together. The two may be either easttogether or in sections and put up as shown. The smoke after reachingthe bottoni of the pipe I is prevented from escaping with the water bymeans of a Water-seal, U.

I'Iavino thus described ni f invention I claim` The combination ofthestack, the pipe I7 and the water-pipe II with the Water-tanks N andhollow screw-shafts, substantially as set forth.

In testimony whereof I affix my signature in presence oi" two witnesses.

WILLIAM VOGEL.
